Utility in Utilities?

Are Downtown businesses currently without power involuntarily sacrificing for tonight's CMA awards?  A tweet I read earlier today from News 2's Christian Grantham seemed to indicate that power to CMA is assured while power to other establishments is not.  Some businesses may be without power until tomorrow.  I don't know how the power grid operates, but I would like to know if power is being rerouted from smaller businesses to Sommet Center.  If one of the selling points for having CMA Downtown is money it will bring to Downtown businesses, but Sobro is browned out, how are the affected establishments benefiting from CMA?
